Many years ago there lived two brothers in London. They were both very rich. They had 1 ideas about money. They were quarrelling（争吵）about what would happen if a poor man could 2 a million pound note. One thought that anyone with such a note would have 3 he wanted; the other thought that it would be 4 for him to get anything with the note（钞票）.They couldn’t agree with each other. So they 5 to make a bet (打赌).
It happened that a young man named Henry was wandering through the street that day, who had come to Britain only chance. 6 home and job, he looked pale（苍白的）and 7 . Suddenly he saw an apple 8 away by a child. The man was so hungry that he was thinking of picking it up to eat. Just as he was 9 out his hand, he heard a voice calling him.

Here are two letters to George and his replies.

Dear George,
I’m fourteen and I’m much shorter for my age. What’s worse, I’m very fat. I want to be 55 kg and to be taller and then I can go to the school basketball team and enjoy myself. Can you help me?
Bob

Dear George,
I’m learning French but I don’t get good marks. I don’t know why. Sometimes I want to give up, but I know I shouldn’t because languages are going to be very important. What should I do?
Alice

Dear Bob,
Don’t worry if you’re shorter than your friends. Teenagers grow at different times. It doesn’t matter how heavy you are. You are still the same person. Plan your meals with your mum, and she can help you lose weight. Also, try taking more exercise.
George

Dear Alice,
You’re right. You should never give up, and I’m sure that you’ve made more progress than you think. You can talk to your teacher and ask her what you should do to get a better grade. Talk to your friends who are good at French. Find something that helps you.
George

The panda is one of the animals most in danger. There are about 1,000 pandas living in nature reserves today. Zoos and research centers look after about 160 pandas. Scientists are studying how they live and more baby pandas are born in the zoos.
Pandas live in the forests and mountains of Southwest China. They mainly live on bamboo, and each panda needs to eat a lot of bamboo every day. The area of bamboo is becoming smaller for many different reasons, so pandas have less and less land to live on. Pandas don’t have many babies, and baby pandas often die. The situation is becoming very serious.
Our government is working hard to save pandas. There are more than 30 nature reserves to protect pandas but these are not enough. The government has made a new plan to help pandas. The nature reserves will be bigger and the bamboo will grow better. Then the pandas will have enough food to eat and enough places to live in. Pandas born in the zoos may go back to live in the nature reserves.
Most people love pandas. The panda is one of the best-known animals in the world. It is the symbol for the World Wide Fund for Nature. The WWF works to protect all animals in danger, so the panda has become the symbol of all animals in danger. There is still a long way to go to save the panda. Think of other animals in danger such as tigers ,whales, turtles and elephant—we need to save the panda, and we need to save them, too.
【小题1】Paragraph 2 is mainly about________.

A．why pandas are in danger

B．why baby pandas often die

C．how to protect all animals

D．how to plant more bamboo

【小题2】The government is trying ________to help the pandas.

A．to build more zoos

B．to send more scientists

C．to make bigger nature reserves

D．to ask the WWF to work in China.

【小题3】________is the symbol for the World Wide Fund for Nature.

C．The elephant

When you see the girl for the first time, you may think she is a boy. She is very outgoing（外向）. Who is she? Wang Meng, the Chinese top skater.
On the evening of February 26th, 2010, Wang Meng first got to the finishing line in 1 minute and 29.213 seconds in the women’s 1000 meters short track speed skating final（短道速滑决赛）at the Vancouer Olympic Winter Games（温哥华冬奥会）. After she succeeded in the 500-meter and 3000-meter races, she won her third gold medal this time. With this one China won four gold medals in the women’s short track speed skating. That helped China first win the team gold medal in Winter Olympics history.
Just before the final race Wang Meng caught a bad cold and coughed terribly. With the words of “You can, you can do!” she won at last. She said, “I really feel these three gold medals belong to my team, to China. It was with the help of my team that I won the prize.”
Though Wang Meng is only twenty-four, she has been the most successful Chinese skater. Chinese are proud of her and her team. We hope she will be faster in Sochi Olympics in 2014.

Sixteen years ago a boy gave me an important gift. 【小题1】_________
It was the early autumn of my first year at a middle school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.

参考词汇：低碳low carbon 纸巾tissue 手帕handkerchief
注意：词数80-120(不含开头和结尾所给出的字数)；可适当增加细节了，以使行文连贯；开头已为你写好，不计入总词数。

（6分）据图回答下列问题：

（1）据图1，若某植物幼苗已表现出向光性，且测得其向光面的生长素浓度为m，则背光面生长素浓度范围是。
（2）据图1可知，

除草剂灭草的原理是使杂草的生长素浓度大于（填图1中字母）。
（3）在探究生长素促进插条生根的最适浓度时，一名技术人员用几种不同浓度生长素溶液处理插条基部，然后在沙床中培养，观察生根情况。图2为生长素促进枝条生根的情况。请结合图1判断，在下列各项浓度值中，最好选用（）

B．6 mg·mL^-1

C．9 mg·mL^-1

D．4.5 mg·mL^-1

（4）生长素的主要作用是促进细胞纵向伸长，其作用机理如图3所示，请回答下列问题：

①生长素作用的第一步是与细胞膜上的受体结合，形成“激素—受体复合物”，这一过程体现了细胞膜的              功能。
②实验发现，细胞在持续生长过程中，细胞壁将发生一定变化，出现这种现象的原因是由于              （填细胞器）为细胞壁添加了新的成分。
③此外，Ca²⁺还能激活细胞中的转录因子，它进入细胞核后，能引起         酶催化mRNA的合成。

（10分）某生物兴趣小组为研究某植物生长发育过程中植物激素间的共同作用，进行了相关实验。
（1）下图为去掉其顶芽前后，侧芽部位生长素和细胞分裂素的浓度变化及侧芽长度变化坐标曲线图，据图分析：

①激素甲代表的是              。
②高浓度的生长素和细胞分裂素对侧芽萌动分别起的作用是         。
（2）为研究根的向地生长与生长素和乙烯的关系，该兴趣小组又做了这样的实验：将该植物的根尖放在含不同浓度的生长素的培养液中，并加入少量蔗糖做能源。发现在这些培养液中出现了乙烯，且生长素浓度越高，乙烯的浓度也越高，根尖生长所受的抑制也越强。
①该实验的因变量是          。
②为使实验严谨，还需要另设对照组，对照组的处理是          。
③据此实验结果可推知水平放置的植物根向重力生长的原因是：高浓度的生长素诱导产生了乙烯，从而          。
